KRUGER NATIONAL PARK, South Africa (AP) — Hippos in South Africa's biggest wildlife park are increasingly grazing during the day rather than staying in rivers and pools as usual, a sign of an intensifying drought expected to kill some animals in the weeks ahead.

However, officials in Kruger National Park described the extremely dry period as a natural way of regulating wildlife populations. And while the park's management makes water available to animals in some parts of the park, they don't plan any major intervention to try to save animals from a drought afflicting southern Africa.
